These puppies are big! For fist crack and offwidth aficionados, Big Bro's from Trango are your way to go! The expanding tube chock design is stable, lightweight, easy to use and strong. Because of their stable nature when they're placed correctly they're almost impossible to dislodge when you're grunting by them, and they make a nice smooth rope guide at the lip of a roof. Their expansion range is phenomenal—a #5 Big Bro has greater range than an entire set of traditional cams!
Craig Luebben, the designer of the Big Bro, died in a tragic guiding accident in August of 2009. His royalty stream will go directly into a 529 college fund for his beloved daughter Giulia. Every Big Bro you buy will contribute money into Giulia's college fund. Just for fun, we asked Jeremy Collins to draw a caricature of Giulia that we're engraving on all of the Big Bro's.

If you're like me and enjoy body scrumming up a d&w (deep and wide) offwidth then Big Bros are worth the investment. My partner and I recently found a virgin offie smack dab in the middle of a sport climbing crag after some scouting we made the first ascent (we think cause no self-respecting sportie would submit their body to such torture) using BBs. For their range and value, four thumbs up way up from two sick offwits!
After a while of fidgiting with these in safe conditions these can be your best choice for range and value if the conditions permit. A good way to set them is to wiggle them around then tightenthem then wiggle them some more then tighten again repeat untill secure. Works best if you can find a bump to help place. Definitely hard to use on lead if never had practice with.
I got the #4 Big Bro to expand my gear range. At its smallest it is like a tipped out #6 cam (BD or Wild Country). Sometimes it is just what you need!
I thought the big bro would be much easier to place and get a bomber placement in an off-width than it is. I had trouble placing it in the off-width I thought it would work well for. But I have another one in mind and I think it should work for that one. Hopefully it will but so far it hasn't done me much good, just really big and expensive! Still love how badass it looks though, lol.
